Sports Betting Law Changes & Timeline
From the 1992 PASPA ban to 35+ legal states in 2026 — the fastest legal expansion in American gambling history

The Speed of Expansion
No area of American law has changed as rapidly as sports betting. In May 2018, legal sports betting existed in exactly one state (Nevada). By March 2026, more than 35 states have authorized some form of legal sports wagering, and the industry generates over $100 billion in annual handle. This pace of expansion is unprecedented in the history of American gambling regulation.
The expansion has followed a predictable pattern: states with existing casino infrastructure moved first (New Jersey, Pennsylvania, Indiana), followed by states seeking new tax revenue (New York, Illinois, Ohio), and then smaller states looking to prevent revenue leakage to neighboring legal markets (Kansas, Kentucky, Vermont). The holdout states — California, Texas, Georgia, and a handful of others — face unique political dynamics that have blocked legalization despite strong public support.
Legislative Timeline
Professional and Amateur Sports Protection Act (PASPA) signed into law, effectively banning sports betting in 46 states. Nevada, Oregon, Delaware, and Montana receive narrow exemptions.
DOJ Office of Legal Counsel issues opinion that the Wire Act applies only to sports betting, opening the door for states to legalize online casino games and lottery sales.
New Jersey begins legal battle to legalize sports betting at casinos and racetracks, challenging PASPA's constitutionality.
Supreme Court strikes down PASPA in Murphy v. NCAA (6-3 decision). States gain authority to legalize and regulate sports betting.
New Jersey and Delaware launch legal sports betting within weeks of the PASPA ruling. New Jersey becomes the first state outside Nevada to take a legal sports bet.
West Virginia, Mississippi, Rhode Island, Pennsylvania, and New Mexico launch sports betting. Most begin with retail-only operations.
New Jersey launches mobile sports betting, quickly surpassing Nevada in monthly handle. Indiana, Iowa, Oregon, and New Hampshire go live.
COVID-19 pandemic temporarily shuts down retail sportsbooks but accelerates mobile betting adoption. Colorado, Illinois, Michigan, Montana, Tennessee, and Virginia authorize sports betting.
New York launches mobile sports betting with a 51% tax rate and limited licenses (9 operators). Arizona, Connecticut, Louisiana, Maryland, South Dakota, Washington, and Wyoming go live.
Kansas, Ohio, and Massachusetts authorize sports betting. Ohio launches January 1, 2023. The industry surpasses $100 billion in annual handle nationally.
Massachusetts, Ohio, and Kentucky launch mobile sports betting. North Carolina authorizes mobile betting. ESPN BET launches through Penn Entertainment partnership.
North Carolina launches mobile sports betting (March 2024). Vermont launches through a state-operated model with limited operators. Missouri voters approve sports betting via ballot measure.
Missouri launches sports betting operations. Several states consider tax rate adjustments — Illinois proposes graduated rates up to 40%. Florida's tribal compact sports betting continues legal challenges.
Industry matures with 35+ legal states. Focus shifts from expansion to regulation refinement: responsible gambling mandates, advertising restrictions, and tax optimization. Several holdout states (California, Texas, Georgia) continue to resist legalization.
Key 2025-2026 Developments
Tax Rate Battles
As the industry matures, the most contentious issue has shifted from legalization to taxation. Illinois proposed increasing its operator tax rate to a graduated structure reaching 40%, which would make it one of the highest-taxed markets in the country. Operators have pushed back aggressively, arguing that high taxes reduce promotional spending, worsen odds for consumers, and drive bettors to illegal offshore sites.
New York's 51% tax rate remains the highest in the nation and has generated enormous revenue ($1+ billion annually) but at the cost of limited operator competition and fewer promotional offers for bettors. Other states are watching New York's model closely to determine whether high-tax, limited-license approaches generate more long-term revenue than low-tax, competitive markets.
Responsible Gambling Mandates
2025-2026 has seen a wave of responsible gambling legislation across legal states. Common provisions include:
- Mandatory self-exclusion programs with cross-operator enforcement
- Deposit limits and loss limits that bettors can set (and that require a cooling-off period to increase)
- Restrictions on advertising during live sporting events or targeting under-25 demographics
- Required funding for problem gambling treatment programs (typically 1-2% of tax revenue)
- Bans on certain bet types (e.g., player prop bets in college sports)
The Big Holdouts
Several large-population states have not legalized sports betting, representing the biggest remaining expansion opportunities:
- California: Two competing ballot measures failed in 2022 — one backed by tribal casinos (retail only) and one backed by online operators. The tribal-vs-commercial divide makes future legislation difficult.
- Texas: Despite strong public support, the Texas legislature has not advanced sports betting bills. Constitutional amendment requirements and opposition from social conservatives have blocked progress.
- Georgia: Multiple bills have been introduced but none have passed. The state constitution requires a two-thirds legislative vote and voter referendum to authorize new forms of gambling.
- Florida: The Seminole Tribe's compact includes mobile sports betting, but it has been challenged in federal court. The legal status remains uncertain.
What to Watch
- California 2026 ballot: New ballot initiatives for sports betting are being organized for the 2026 election cycle. California alone could represent $3+ billion in annual handle.
- Federal advertising regulation: Congress is considering bills to restrict sports betting advertising, particularly during live sports broadcasts and on social media platforms popular with minors.
- Interstate compacts: As more states legalize, pressure grows for interstate compacts that would allow shared liquidity pools, particularly for online poker and niche sports markets.
- Tax rate convergence: States are likely to adjust rates toward a sustainable middle ground (15-25%) as data accumulates on the relationship between tax rates, operator competition, and consumer outcomes.
